Hi Chief and thanks for your reply on the Volvo Penta
Unfortunately the Volvo workshop manual is not clear on that point.
All it says is: "The fuel injection pump pulley has two adjustment marks
(A and B) and two keygrooves. The keygroove on the same side as the
relevant adjustment mark must always be used".
Apparently the engineer
on the job thinks that either A or B is for the
setting position for a turbo engine
and the other is for a non-turbo.
The engine has been played around with by an unqualified guy prior to
taking over, and he just wants to confirm what A & B means.
Do you or anyone else have any further comments please???
